I wouldn't have a problem with my wife not wanting anything to do with it, in fact that IS pretty much where my wife and I are at. The "problem" in the OP, is that the wife wasn't happy with just not being a part of it, but instead felt compelled to make Leslie feel like shit about it the night before - again something that I also see with my wife from time to time.
Wanting nothing to do with it is perhaps understandable and livable, but being mean and hurtful about Leslie going out is a bit more than that isn't it?
Doormat, as Paula said, your viewpoint IS wanted here, whether it is flattering to us or not, hurtful to us or not, it is an honest opinion from a woman who loves one of us.
